Release 8.0.28 — The thorny path to perfection

8.0.28 is a quality-of-life update. Construction machines have received a major visual overhaul, with improved Blueprint previews and redesigned GUIs across the Builders module. The update also improves the Heat Exchanger, changes how Pumps select fluids, and fixes several issues.

Changes:

• Overhauled Builder, Filler, Quarry and Architect Table visuals. Added status lights, animated construction effects, highlighted work locations and Architect Table scanning effects, making it easier to see what each machine is doing.
• Improved Blueprint and Template previews. Saved designs now have detailed 3D previews in tooltips and construction interfaces, with better rendering of pipes, fluids and other complex blocks.
• Added an optional Filler world preview. A new button in the Filler GUI shows a translucent projection of the selected pattern before and during construction without changing the actual work.
• Redesigned the Replacer GUI with a 3D preview of the proposed Blueprint changes and clearer Replace and Remove controls. Players can inspect the result before applying the replacement.
• Improved the Electronic Library with a draggable scrollbar, readable Blueprint and Template names, more useful tooltips and 3D previews when hovering over saved designs. Names and other saved details are now preserved more reliably when designs are copied or downloaded.
• Reworked the Heat Exchanger with a new block model and an improved GUI. It now shows four separate fluid tanks, an animated processing indicator and four slots for filling and draining fluids with containers such as buckets and Fluid Shards. The GUI can also be opened from connected exchanger sections.
• Improved Pump fluid selection. Pumps now prioritize oil and other non-water fluids over water, prefer continuing to pump the same fluid where possible, and can extend their shafts down to the bottom of the world. Inaccessible waterlogged blocks and the Pump's own tubes are ignored during fluid searches.
• Improved in-game Help panels. Help text now fits smaller screens more reliably, and contextual help highlights specific Gate, Builder and Filler controls instead of covering entire interface sections.
• Increased the maximum stack size of IC2 Fluid Cells to 64 on Minecraft 1.19.2 Forge. Fluid-handling automation still needs to process the cells individually.

Fixes:

• Fixed Combustion Engines crashing on Minecraft 1.19.2 Forge when the last unit of certain fuels is consumed.
• Fixed engine rotation with a wrench across supported versions. Wrench interactions are no longer intercepted by the Stone Engine GUI, and sneak-wrenching a Creative Engine rotates it instead of changing its power output.
• Fixed Heat Exchangers failing to update their connected sections after blocks are added, removed or rebuilt. Their fluid displays and progress indicators now update correctly, and stored fluid containers are returned when the machine is broken.
• Restored JEI recipe shortcuts in the Assembly Table, Programming Table, Integration Table, Auto Workbench, Advanced Crafting Table and Heat Exchanger interfaces on NeoForge. Clicking the relevant progress or energy display opens the corresponding recipes.
• Fixed the Programming Table glass appearing missing or being rendered incorrectly on some versions.
• Fixed Architect Table and Replacer name fields taking keyboard focus automatically or keeping focus after the player clicks elsewhere.
• Fixed occasional pipe interaction crashes when a pipe's block entity is temporarily unavailable during chunk updates, and improved the handling of invalid saved Blueprint data.
• Improved addon Gate compatibility. Custom Gate statements and parameters can display their names and icons correctly, and parameters without a default value no longer cause broken or blank configuration slots.
